WEIGHING-SCALE.

Application filed June 13,1905. Serial No. 265,106.

To all whom t 'may concer/t:

Be it known that I, ZACHRY T. GRAGG, a citizen of the United States,residing at Oklahoma city, in the county of Oklahoma and Territory ofOklahoma, have invented new and useful Improvements in l/Veighing-Scales, of which the following is a speciiication.

This invention relates to weighing attachments for cars, wagons, andother vehicles, and has for its object to provide an inexpensive,durable, and eflicient device of this character capable of being readilyattached to the vehicle and by means of which the weight of the load orcontents of the vehicle may be quickly and accurately ascertained.

A further object of the invention is to provide means for disconnectingthe operative parts of the weighing mechanism when the device is not inuse and means for varying the length of the scale-lever.

A still further object is to provide a plurality of sectionalsupporting-boxes mounted on opposite ends of the vehicle-holsters andmovable vertically to elevate the wagon-box when the scale-levers areoperatively connected to the scale-beam.

l/Vith these and other objects in view the invention consists in theconstruction and novel combination and arrangements of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in form, proportion, and minor details of construction may beresorted to without departing from the principle or sacrificing any ofthe advantages of this invention.

In the accompanying drawings, forming a' part of this specification,Figure l is a side elevation, partly in perspective, of a wagon, showingmy improved weighing attachment applied thereto and in position forweighing the contents or load of the wagon-box. Fig. 2 is an endelevation, partly in section, of one of the supporting-boxes, showingthe man-I ner of attaching the same to the bolster and wagon-body. Fig.3 is a plan view of Fig. 2 with the wagon-body removed. Fig. 4 is asectional side elevation of Fig. 3 as seen from the side of the wagon,portions being broken away to expose the interior construction of thesupporting-boxes. Fig. 5 is a similar view showing one of thebox-sections in elevated position. Fig. 6 is a sectional plan view ofone of the lifting rods or bars. Fig. 7 is a perspective view of one ofthe scalelevers detached. Fig. 8 is a sectional elevation of the slottedend of the scale-levers. Fig. 9 is a transverse sectional view taken onthe line a; y of Fig. 7. Fig. l0 is a view in elevation of a portion ofthe footboard of the wagon-box with the guide-loop in position thereon.Fig. l1 is an end view of Fig. l0 looking in the direction of the arrow.

Similar letters refer to similar parts in all the iiguies of thedrawings.

' The improved weighing device, which may be used in connection withwagons, cars, platforms, and the like is shown, by way of illustration,attached to an ordinary farmwagon, in which A indicates the wagon-box,and B the running-gear.

Secured to the opposite ends of the front and rear wagon-bolsters t arefulcrum-boxes, preferably formed in two sections c and c, the lowersection o of each box being rigidly secured to the adjacent bolster, asby bolt j, while the section a is mounted for vertical movement betweena pair of spaced flanges Sr and S on the stationary section and providedwith a vertical extension a and a lateral projection or wing K forattachment, respectively, to the side and bottom of the wagonbody, asshown.

The lower sections a of the boxes are further retained in position bymeans of depending lugs g, which engage correspondinglyshaped recessesin the bolsters b, there being an inclined guide-lug p', disposedbetween the flanges S and S at one end of each stationary section and asocket G at the opposite end thereof adapted to receive a stake whenneeded.

Extending transversely of the wagon-body through auxiliary bolsters band journaled in bearings h in the spaced flanges S and S are rocking orlifting bars h the opposite ends of which extend beyond the flanges Sand are provided with squared terminals 7L, for the purpose hereinafterreferred to.

Rigidly secured to the rocking or lifting bars L and mounted to turnwith the latter between the vertical flanges S and S are doubleeccentric levers m, provided with knifeedges m', adapted to engage thebearingfaces of suitable studs n and n', preferably formed integral withthe upper and lower IOO sections, respectively, of the fulcrum-boxes.The movable box-section a is provided with a depending guiding-spur p,which bears against the lug p and serves to guide said box-section whenmoved to operative and inoperative positions by the movement of theeccentric levers m, attention being. called to the fact that the lug palso bears against the stud n, thereby preventing lateral movement ofsaid section. Secured to or formed integral with the movable section ofeach box is a depending lug o, which enters the recess formed betweenthe flanges S and S and serves as an additional means for guiding saidmovable section, there being an opening o formed in the lug o, adaptedto register with corresponding openings o in the flanges S and S whenthe movable section is lowered to permit the insertion of a bolt or pinfor locking the two sections together when the Weighing attachment isnot in use. The base of the stationary section and the top of themovable section are also curved or hollowed, as indicated at r in Fig. 4of the drawings, to permit the free turning movement of the eccentriclevers.

Secured to thefootboard C of the wagon is a bracket provided withinwardly-extending guide-ianges c', between which is slidably mountedthe enlarged head c of the scalebeam guide d, vthe latter having one endthereof bent upwardly and terminating in a vguide-loop adapted toreceive 'the scale-beam e', as shown. y Pivoted to the head c is apullrod e, havingits upper end bifurcated and attached to the scale-beame', the latter, being graduated in pounds and fractions thereof in theusual manner and provided with a balance-block f', poise e, and swingingpoiseholder u.

Connecting the scale-beam e and the lifting rods or bars h are removablelevers g, one end of each of which is provided with a squared socket forthe reception of the corres ondingly-squared end of the adjacent ro h,while the opposite end thereof is provided with an adjustable sleeve orcollar g', connected,through the medium of a hookf, to the scale-beam,as shown. The reduced ends of the scale-levers g are provided withelongated slots g, ada ted to receive clampingbolts which exten throughthe adjustable sleeves or collars and serve to clamp the latter inadjustable position so as to maintain uniformity of length of saidlevers under various conditions.

' When it is desired to weigh thel load or contents of the wagon-body,the head of the scale-beam guide is inserted between 'the guide-flangesc with the upstanding loop embracing the adjacent end of the scale-beam,after which the levers g are fitted over the ends of the lifting-rods hand the extensions or adjustable collars connected to the hook byexerting a downward pressure on said collars. As the ends of the leversg are forced downwardly into engagement with the'hook f the rods, h arepartially rotated, thereby causing the knife-edges of the eccentric.levers to engage the bearings in the studs n and n and elevate the,movable sections of the Ysupporting-boxes, together with the wagonbox,to the position shown in Figs. 1 and 5- that is to say, in position toweigh the load. After the gross weight is thus obtained the load isremoved from the wagon and the latter weighed, the weight of the wa onbeing deducted from lthe gross Weight to determine the net weight of theload of grain or other material in the vehicle.

The attachment is readily disconnected by removing the scale-levers g,which permits the movable boxsections carrying the wagon-body to returnto the position shown in Fig. 2, the guide d and pull-rod e beingsubsequently detached and, together with the scale-levers, placed withinthe wagon-box for further use.

While the scale attachment is particularly designed for attachment .tofarm-wagons, it is obvious that the same may be used with equally goodresults in connection with trucks, drays, cars, and a great variety ofvehicles with but very slight modification and without departing fromthe spirit or sacrificing any of the principles.

Having thus described the invention, what is claimed is 1. In weighingmechanism, the combination with a vehicle-body, of the running-gear,fulcrum-boxes interposed between the running-gear and body, doubleeccentric levers journaled in the boxes and forming fulcrums, ascale-beam, and levers connecting the fulcrum-levers and scale-beam.
